The trajectory is propagated between control points by solving Kepler’s problem [8]. The Sims-Flanagan transcription, when used with a NLP solver such as Sparse Nonlinear Optimizer (SNOPT) and a suitable initial guess, is very fast and robust. It is considered to be a “medium-fidelity” transcription and is
